Aifake Order Vacuum Coating Thickness Measuring System

When it comes to Aifake, we believe that everyone in the vacuum coating industry knows it. Aifake Vacuum (Chengdu) Co., Ltd. is also an old friend of Linshang Technology. Since 2017, we have been ordering non-contact vacuum coating thickness measuring systems produced by Linshang Technology. Recently, two non-contact vacuum coating thickness measuring systems have been ordered again.

This non-contact vacuum coating thickness measuring system is based on the principle that the transmittance (optical density) of the material is proportional to the coating thickness. The uniformity of the material is monitored by monitoring the optical transmittance (optical density) of the material. The vacuum coating thickness measuring system adopts RS485 communication interface and supports the standard MODBUS communication protocol. It can be connected to the PLC of the vacuum coating thickness measuring system to realize closed-loop control.
       From the customers, we know that the characteristics of various vacuum-plated films are different. At present, the films we have contacted are aluminum, gold and conductive films. As for the base material of the film, it is divided into a transparent base material and a translucent base material. The non-contact vacuum coating thickness measuring system for this optical transmittance principle is also specially customized due to the characteristics of the material.
       The structure of Linshang non-contact vacuum coating thickness measuring system is composed of a measurement and console and a man-machine interface control box. The measurement and console mainly includes a light source probe, a receiving probe, a controller and an aluminum profile frame. As shown below:

Due to the different widths of different films, if the position of the test points is fixed according to a certain width of the film. When testing other films of different widths, it may appear on the wide film and the test points are unevenly distributed or there are no test points on the edge of the film. According to the needs of customers, the engineers of Linshang Technology changed the structure of the aluminum profile of this non-contact vacuum coating thickness measuring system and made the test points in a movable way, which solved the customer's problem. As shown below:

Linshang technology non-contact vacuum coating thickness measuring system has been widely used in roll vacuum coating machine, coating production line, glass production line and other equipment. That is, the uniformity of the coating film thickness can be measured by the optical density value. It can also be used to detect the transmittance of transparent materials such as glass.
